Re: [TRNSYS-users] TRNSYS crashes after several runs

[David BRADLEY via TRNSYS-users <trnsys-users@lists.onebuilding.org>]

Victor,

  I have never run into something like this before. It is a little odd that it is the Simulation Studio crashing; the Studio doesn't really do anything when the simulation is progressing. Once a simulation is launched the Studio is idle. Also, when the Studio crashes, does TRNExe continue to run? The two aren't linked in any way so if one crashes the other ought to continue on.

  My only guess is that there is some output file that is accumulating from run to run. It is possible to set some of the printer components so that they append to an existing file instead of overwriting the file on each new run (for example Type25 parameter 7). Unless there is some reason to keep all the results in a single file, you can select the "overwrite" option. One easy way to check if the problem is one of the printers would be to make some consecutive runs after temporarily deleting all the devices that write to output files.

kind regards,

 David

Dear all, 

I have a TRNSYS model with a Type 56 building and a solar collector system attached to it.

The original model was designed in TRNSYS 16, but I have recently managed to move it to TRNSYS 17 (the relatively difficult part was to update Type 56 to TRNSYS 17).

When I run the model once, everything works fine. The problem starts when I do several consecutive runs (without any changes in the parameters). Sometimes the second run works perfectly as well, but on the third run the Simulation studio crashes without any warning.

The only way I found to run many times the model was deleting all the files which are generated after the previous simulation has finished. 

Could you suggest something in order to avoid manual deleting of the output files? 

My concern is than in case I would like to do a parametric run or GenOpt optimization, will I have to manually delete the output files every time?

Thank you in advance. 

Regards, 

Victor
